   <p class="para">
    如果指令 <a href="sybase.configuration.html#ini.magic-quotes-sybase" class="link">
    magic_quotes_sybase</a> 为 ON，它会完全覆盖 <a href="info.configuration.html#ini.magic-quotes-gpc" class="link">magic_quotes_gpc</a>。
    所以即使 <span class="function"><strong>get_magic_quotes_gpc()</strong></span> 返回 <strong><code>TRUE</code></strong>，双引号、反斜杠或 NUL 都不会被转义。
    只有单引号会被转义。
    这种情况下它们看上去像：<em class="emphasis">&#039;&#039;</em>
